Leaving Your Current Factor You need to consider the fees associated with switching before committing to the change. Once you've decided to leave your current factor, you will need to give notice. All factoring companies require written notice to terminate the contract.
Get a Release Letter: Once all obligations are fulfilled, ask for a release letter from the factoring company. This document should state that you have fulfilled all contractual obligations and that the factoring company has no further claim on your invoices or receivables.
This will help you understand your rights and options. Contact the factoring company. Talk to the factoring company directly and explain the situation. Ask them why the release hasn't been issued yet and when you can expect it. Be polite and professional, but be firm in your request. Get everything in writing.
